Similar material diffuse colors inconsistent with different light intensities

Recommended Posts


I'm trying to match the colors of a material with a diffuse texture, and a material which has a matching diffuse color.

However, I'm not getting a lot of detail on the diffuse texture under the default light intensity, and when I ramp it up, the two materials change colors at completely different paces.


As you can see, I'm getting them to mostly fine on the left side, but I can't make out any facial detail, on the right you can make out facial detail, but it also illuminates the rest of the skin way too brightly.

Meanwhile in Blender I can achieve this:



With blender render and the default light. Similar results with a hemi-light. No need to ramp up the intensity, but even if I do, all materials brighten equally:


Using the exact same texture both in blender and babylonjs as well. Lambert material in blender, default in babylonjs.

This is the lighting and material code:

var light = new BABYLON.HemisphericLight("hemilight", new BABYLON.Vector3(0,1,0), scene);
    light.intensity = 1; //3-4 to see any revelant facial detail

var skincolor = new BABYLON.Color3.FromHexString(globalSkin);

//meshes array are just different body elements of the same body

meshes[0].material.diffuseColor = skincolor; //skin color applied everywhere else besides the front face
meshes[0].material.specularColor = new BABYLON.Color3(0, 0, 0);
meshes[1].material.diffuseColor = skincolor;
meshes[1].material.specularColor = new BABYLON.Color3(0, 0, 0);
meshes[2].material.diffuseColor = skincolor;
meshes[2].material.specularColor = new BABYLON.Color3(0, 0, 0);

var f = new BABYLON.StandardMaterial("myMaterial", scene); //face texture
f.specularColor = new BABYLON.Color3(0, 0, 0);
f.diffuseTexture = new BABYLON.Texture("../u/"+id+"/f.jpg", scene);
meshes[3].material = f;
